Abstract In underground grouting engineering，phase interfaces in different types of grouts and water have different characteristics；the characteristics of slurry-water phase interface have great significance to describe the mechanism of grouting for stopping up water and build a numerical model of slurry mixing zone. By analyzing the phase interface morphologies of different slurries，the characterization methods and application types are obtained. By the laboratory experiments，determination test of cement-silicate mixed area is carried out；and characterization of cement-silicate grout phase interface in dynamic water is obtained. By analyzing the experimental data，phase function is decomposed into height function and width function in order to describe the geometric features；besides，the influencing factors are analyzed. The results will be helpful to develop the mechanism of grout and block water as well as establish the numerical model of slurry-water interface.
